Specification of Letters Patent.

Patented March 20,1906.'

Application ned August 2, 1904. serial No. 219,250.

To a/ZZ whom it www concern.- v v Be it -known that LFROBERT MoCoY, a citizen West Twenty-fourth street, New York city, in the State of New York, .have invented a Perfect-Level-Surfacing Machine to be Used on Bowling-Alleys and Floors of Any Kind,

of which the following is a specification.

My invention relates to improvements in and though sus-l l ceptible of many different uses has for its pri- "mary object the leveling and polishing ofl level surfacing machines,

bowling-alleys, where it is essential that the surface be not only level, but polished toa highudegree. 1

Y My invention is especially adapted for use on alleys or floors which have become worn or uneven and embraces means for removing the old shellac or finish therefrom, scraping and leveling the same, the leveled surface.

My invention further contemplates means whereby the machinev support or. carriage may travel longitudinally relative to the surand finally polishing face without contacting or marring the same,

while permitting the working parts of the machine to remain in juxtaposition relative to the surface. l

Further novel features will be brought out `in the detail'description following when read in connection with the accompanying drawings, forming a part hereof, and wherein a preferable embodiment'of the invention is disclosed for the purpose of illustration.

In the drawings, Figure 1 designates a top plan view of the carriage or support in posihaving connected Fig. 2 is a cross-sectional view on the line 2 2 of Fig. 1.

Fig. 3 is allongitudinal sectional view on the 'line 3 3 of Fig. 1. the scouring or scraping .device detached; and

Fig. 4 is a detail view of Figs. 5 and 6 are detail views in elevation yand cross-section, respectively, of the leveling device detached. I j

Referring now more particularly to the drawings, wherein like reference characters designate corresponding parts throughout the several views, A designates the support for the alley-surface, having the usual spaced gutters Al extending' longitudinally thereof,

and B representsl the floor or surface proper mounted upon thesupport between the respective gutters.

C C represent portable tracks having transversely-extended bottom portions c, curved of the United States, residing at 230 complementary to the curvature-of the gutf ters and adapted tovlooselyrest-therein.

D represents the carriage of my machine,

y' the frame of which comprises spaced longitu- 6 o 'dinal bars D ing therebetweenand connected in any sultand transverse bars D2, extendable manner at their ends to said longitudinalA bars. Arranged intermediate said transverse bars are cross brace-bars E E, centrally connected and secured in any suitable manner at their ends to the respective longitudinal bars. OutWardly-extended reduced portions d on the bars D constitute axles for antifriction -rollers F, adjustably mounted 7o" thereon in any desired manner, as by nuts d engaging the screw threaded ends of said axles 0l'.

vGr represents threaded bolts extending through the longitudinal bars D, said bolts having a screw-threaded portion g, to which are adapted to be. interchangeably connected the scouring or scraping, leveling, and polishing devices, respectively.

H represents-the scouring device compris- 8O ing a back-support h and downwardly-projecting closely-associated metallic pins h.

I represent oppositely-disposed inverted- Z-shaped bars, the lower angle portion t of Which are connected in any desired manner to outwardly-projecting portions h on the scrap er H, and the upper angle portions i have suitable aperturesstherein 'ada ted for the reception of the screw-threade .ends of the bolts G. A

J represents a'leveling device comprising the top member J and a series of longitudinally-extended rows of thin lfiat blades j, preferably s ringy in character and the resiliency thereof eing adjustable-through the means about to be described J designates a plate having a series of apertures extending throughout the same, one for each blade j, and -the wall surrounding said apertures being depressed for the -10o easy insertion .of said blades.

K designates adjusting-screws extended between the members J and J, whereby the said late J. may be vertically adjusted to simuftaneously adjust the resiliency of each l ofsaid blades y'. The member J has outwardly-extended portionsj at its respective sides, to which are secured inverted Z- shaped bars similar in all respects to the bars I above described.

- L represents the formedV of any suitab IIO olishingl attachment.,

emery-stone, and has at its respective sides outwardly-extended portions Z, to which are secured inverted-Z-shaped members similar in all respects to the bars I before described.

Suitable brace-rods M extend between the respective pairs of inverted-Z-shaped bars I.

From the above it is believed the operation of my machine is obvious. When it is desired to surface the iioor of an alley or the like, the portable tracks are positioned in thegutters thereof and the carriage placed thereupon, the rollers being adjusted to proper position for engaging the respective tracks. The iirst operation being to scour or scrape the floor, the scraper H is connected to the carriage and through the means of the proj ecting pins will remove any shellac or irregular portions from the floor during the longitudinal travel of the carriage. The second operation being to level the scoured floor, the scraper H is removed from the carriage and the leveler J properly positioned thereon. After the iloor has been accurately leveled the polishing device L is properly positioned upon the carriage and will give to the iioor a finish.

Having thus described my invention, what I claim is 1. The combination with an alley bed or support having oppositelydisposed longitudinally-extended cut-out portions constituting gutters, of a pair of spaced rails detachably mounted in said gutters, a carriage adapted for longitudinal travel relative to the alley, rollers for the carriage arranged to engage the rails, and said rails having bottom-supporting portions of the same size and shape as said gutters whereby the former are held in place.

2. The combination with an alley bed or support having oppositelydisposed longitudinally-extended concave cut-out portions constituting gutters, of a pair of rails mounted in said gutters but unattached thereto, a carriage adapted for longitudinal travel along said alley and having antifriction devices for engaging the rails, and said rails having convex bottom portions shaped to snugly rest in the concave gutters,whereby the latter constitutes the only retaining means therefor.

3. In a machine of the character described, the combination with a carriage, of a surfacing device having outwardly-projecting portions, inverted'- Z shaped bars connected with said projecting portions, and verticallyadjustable means on the carriage for adjustably supporting said surfacing device including bolts engaging apertures in the upper angles of said Z-shaped bars.
